Disadvantages of plc technology in home applications

Disadvantages of plc technology in home applications: meters are prone to become bandwidth bottlenecks, susceptible to interference from other appliances, leakage security.

PLC technology, which employs a class of programmable memories for its internal storage of programs, performs user-oriented instructions such as logic operations, sequence control, timing, counting and arithmetic operations, and controls various types of machinery or production processes through digital or analog inputs/outputs.

So plc in home applications will have the disadvantage of being susceptible to interference.

Power Line Communication (PLC for short) is a type of communication that uses power lines to transmit data and voice signals.

The technology involves loading high-frequency signals containing information into an electric current and then transmitting it over a wire, where the modem receiving the information then separates the high frequencies from the current and transmits them to a computer or telephone for information transfer.

Low-speed (less than 1200 bps) power carriers are now commonplace for use in a variety of situations. Using transmission lines as the medium of signal transmission, people use power lines to transmit telephone, telegraph, telemetry, data and remote protection signals.

Because of the high mechanical strength of the power line, good reliability, do not need the line's infrastructure investment and routine maintenance costs, so PLC has a high degree of economy and reliability, in the power system scheduling communications, production command, administrative business communications and a variety of information transmission plays an important role.
